Im building a small stereo system that utilizes a car stereo receiver to power the speakers. I would like to select between a battery and a power supply unit (for when I have an outlet as to not waste battery) to power the system. My questions are 1) can i put a switch between the power supply and battery to select the power source to the receiver and 2) exactly what kind of switch do i need to do this?
